Sugar Purity Testing Saccharimeters
The Rudolph Research Analytical Autopol IZ and Autopol IIZ
Polarimeter for sugar testing
Temperature correction
High quality polarizing prisms
Single or dual wavelength
Autopol IZ Sugar Saccharimeter
- Single wavelength 589 nm
- Perfect for 0.02º Z applications where budget is critical
- Popular for applications that do not require ICUMSA measurement at the 880 nm wavelength
Autopol IIZ Dual Wavelength Sugar Saccharimeter
- Dual wavelength 589 nm and 880 nm
- For sugar mills that perform sugar purity testing according to the ICUMSA non-lead procedure
- A budget saving alternative for applications that do not require the accuracy of more expensive saccharimeters
Sugar Purity Testing Software
Optional Purity software is available for use with a separate Windows PC.. The Purity software and a refractometer also allow dilution on a weight/weight or weight/volume basis which can also be prespecified for each sample name. Each program can be labeled with an alphanumeric and assigned to one of the method keys. The factory operator simply presses the preassigned method key to start measurement.

Dual Wavelengths
The most important feature of the Autopol IIZ is the ability to measure at two wavelengths: 589 nm and 880 nm (NIR). Select 589 nm for conventional analysis using chemicals or lead clarifiers, or select 880 nm for polarimetric sugar measurements in the near infrared (NIR). 880 nm is above the absorption level of most dark sugar factory solutions allowing measurement of filtered but non-lead clarified juices. The dark sample measurement bar gets darker in proportion to the darkness of the sample being measured. When the bar is completely dark the instrument has reached its measurement limit.
Automatic Temperature Correction
Utilizing the temperature probe located in the measurement compartment, temperature correction to 20ºC, 27.5ºC or other user defined temperature is performed easily and automatically by the Autopol IZ and Autopol IIZ.. The probe can be inserted into all 14 style, 40T style, 41T style and 33 style measurement cells.
The Autopol displays the temperature source and type of correction. Utilizing factory programmed temperature coefficients the Autopol can make the following types of temperature corrections:
- A 30° C sucrose sample can be measured by the temperature probe and corrected to 20°C or 27.5°C or a customer defined temperature
- A 29°C sucrose sample in a Type 14 center fill glass cell can be measured by the temperature probe inside the saccharimeter sample chamber and corrected to 20°C
- A Quartz Plate measured at 25°C by the chamber temperature probe and then automatically corrected to 20°C
Temperature Probe Insertion Options
The temperature probe in the sample compartment can be inserted into the polarimeter cell.
Automation and Continuous Sampling
Cells are available in 25mm, 50mm, 100mm and 200mm optical path lengths with fittings for any application.
Pour in Sampling
Stainless steel cells are available in 50mm, 100mm and 200mm optical path lengths.
Optics
No matter which Autopol saccharimeter you choose it will feature the same high quality optics. While other manufacturers use Polaroid plastic dichroic sheet polarizers, Rudolph Research employ Glan Thompson Calcite polarizers in all its models. High quality polarizing prisms are important because they are two of the most critical optical components in a saccharimeter. Polaroid polarizers are made of a polymeric plastic where the molecules are stretches and oriented in a specific direction so as to linearly polarize light. These types of plastic sheet polarizers are cheap, vulnerable to heat and warping, deteriorate from moisture and have greater light absorption than Calcite polarizers. In many cases the plastic polarizers must be replaced in as little as 3 years whereas Rudolph guarantees its prisms over the life of the Saccharimeter. Glan Thompson calcite polarizers are comprised of a carbon crystalline structure similar to diamond and have excellent light transmission characteristics. The quality of these prisms is such that they are guaranteed over the life of the saccharimeter.
Also available the Autopol 589, the Autopol 880 and 880T and the 880 Plus and 880T Plus.
